No Card

I get a, 'No Card' message on the rear screen of my EM1 from time to time, even when there is a card in the slot.
Just updated the firmware hoping that would stop it but I still got it. After switching off and changing cards, got the same message , then changed to another card, no it is OK.
Not ad trouble with the cards before.
Any ideas?

Re: No Card

Sounds more of a camera issue than card, based on what you've said. Wouldn't know how to go about fault finding without the specialised equipment.
I think you've discounted firmware, the only other thing you could do on a DIY basis is to clean the terminals on both the card(s) and at the camera interface. You could try somewhere like Maplin for switch cleaner.

Re: No Card

Thanks Steve, I will try that before it goes back to Oly.

Re: No Card

I've not got my camera to hand to try, but is there some sideways 'wiggle' you can impart to the card, either to induce the fault on a card currently accepted by the camera, or on a card that's not recognised. If you can induce the fault and describe how, Oly will have a better chance at rectifying any issues.

I forgot to ask earlier, are you doing this in the comfort of your home within normal ambient temperatures, not in some god forbidden part of the world where the temperature is out of range, or high humidity another killer for consumer electronics.

In fault finding, again at DIY level, you could get a can of freezer and spray down the side of the card into the camera, see if you can induce the fault, or make it go away. It's quite a common method of finding 'bad' joints.

Re: No Card

Have had this; found cleaning the card contacts with alcohol solved my problem. Worth a try?

Isopropyl alcohol, save the vodka for latter

Also worth getting a cotton wool bud wetted in isopropyl and clean the camera contacts. It takes two to tango!

Both the camera and card contacts are gold plated, just a few tens of microns thick, and should not tarnish. I always handle the card by the plastic, avoiding the plated terminals like the plague. If someone does accidentally touch the contacts, I give the interface a quick wipe with tissue paper, or a micro fibre cloth.

Metho is OK if you buff off the white powdery film that can be left behind. A soft pencil rubber can be used on the SD card contacts first to remove any tarnish (or dull surface).

There shouldn't be any 'tarnish' on the contacts. They're gold and gold doesn't tarnish - even after 1000 years!

That might be the theory, but gold contacts can get a dull, 'oxidised looking' surface after some time (maybe it has something to do with how it was manufactured), & it is that dull surface that can be less reliable for electrical connection. I've had to polish & clean contacts on pcboards when servicing early computer systems & if there is any doubt about contacts for any device, then polish & clean the contacts. That includes battery & camera grips (with gold surfaces).

Re: No Card

Gold is one of the least reactive elements and I suspect the 'dulling' you're referring to is environmental contamination, as a surface deposit.

The plating or electro-deposition is measured in microns, so can be mechanically abraded with continued insertion of the card (both ends of the interface, of course, i.e. the card and the camera) and the underlying base metal will no doubt oxidise. In hi-rel installations an upper limit of mating operations is set, typically 100, then discarded. During test sacrificial 'connector savers' are used, thus minimising degradation to the in-service item on the prime equipment.
